Thanks for sharing this piece from your collection. I've never seen a POM marking with the company designation underneath the bar code. Also, it's interesting to note that the colours used in the bar code do not correspond to the serial number indicated. For example, as far as I can tell the last two digits of the serial number are "83", yet according to the colours used, the last two digits should in fact be "65".
There's been a rather interesting development on the project, and I will keep you all informed!
